henrik.g 7 Posted August 25, 2016 Hey everyone, I am trying to wrap my head around Bullet some more and wanted to clear some questions, so i'm solid there... 1.Units I: I found this info on the web: "A 12 pd started with a muzzle velocity of about 1769 Feet Per Second " If I was to set this up: Then Mass would be 6 and Initial Velocity would be 539, correct? 2. Units 2: If I would want to compute Mass - and lets assume Iron - then I can just check in with Wolfram Alpha and use their 7874kg/m3, correct? 3. Units 3: Glue Strength, is there any "real world" counterpart? Or a formula that describes whats going on, or is this just artistic choice? 4. Settings: Bullet Constraint Iterations: This seems to have an massive impact on the outcome, is this normal? 5. Workflow: Is Object-Merging within the same SOP acceptable? I think with all these connections from left to right is kinda cluttered...? This all leads to my HIP. I have 2 thin sheets of "concrete" or whatever and want a sphere to pass through, yet what ever I do, however low I set Glue Values and so on, everything will collapse, but the Sphere wont pass through? Is there anything I got wrong?? Thanks for any help! Best regards! cantPassWall_v02.hiplc Share this post Link to post Share on other sites
